A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...

Plant communities and succession in Oregon coastal salt marshes

Creator:: Jefferson, Carol A.
Abstract:: The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon. Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...

Plant reproductive ecology and community structure along a subalpine snowmelt gradient

Creator:: Ingersoll, Cheryl A.
Abstract:: The seasonal duration of snow cover is a primary factor influencing the patterns of vegetation in high subalpine and alpine environments, but little is known concerning the responses of plant reproduction and seedling recruitment to gradients of snow-release. Vegetation patterns of a high subalpine site in the Oregon High Cascades...

Growth and replacement patterns occuring among selected dominant species associated with plant succession on Douglas fir clear-cuts

Creator:: Robinson, Myles Canby
Abstract:: Growth and replacement patterns of four successionally important species occurring on Douglas fir clear-cuts were investigated from September 1964 to June 1967. The study was carried out on the Marys Peak watershed located near Corvallis, Oregon. Species used in the study include Holcus lanatus, Senecio jacobaea, Lotus crassifolius var. subglaber,...

Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Reproduction, demography, and habitat characterization of Astragalus peckii (Fabaceae), a rare central Oregon endemic

Creator:: Martin, Elizabeth F.
Abstract:: With little previous research on Astragalus peckii (Fabaceae), a state-listed Threatened species in Oregon, I investigated three facets of its biology which are integral to the conservation and management of the species. First, a four-year demographic study of two large populations revealed increasing population growth at one site (Chiloquin) and...
